A government sample survey plans to measure the LDL (bad)
cholesterol level of an SRS of men aged 20 to 34.
Suppose that in fact the LDL cholesterol level of all men aged 20
to 34 follows the Normal distribution with mean
μ = 110
milligrams per deciliter (mg/dL) and standard deviation
σ = 25 mg/dL.
What is the probability that x takes a value between 107 and 113 mg/dL? This is the probability that x estimates μ within ±3 mg/dL. (Round your answer to three decimal places.)
Choose an SRS of 1000 men from this population. Now what is the probability that x falls within ±3 mg/dL of μ? The larger sample is much more likely to give an accurate estimate of μ.

The LDL cholesterol level of all men aged 20 to 34 follows the
Normal distribution with mean μ=120μ=120 milligrams per deciliter
and the standard deviation is σ=30σ=30 milligrams per deciliter. If
you choose an SRS of 25 men from this population, what is the
sampling distribution of mean cholesterol level of the 25 selected
men.

A lab tested a random sample of 155 chicken eggs for their level
of cholesterol. The average of the sample was 198 milligrams. The
standard deviation of all eggs of this type is known to be 14.1
milligrams. What is the 95% confidence interval for the true mean
cholesterol content of this type of chicken egg?

they survey a sample of n= 25 music major students. participants
respond to a measure of creativity and the average score for the
sample is M=64. it is known that the distribution of creativity
scores for the population of college students is normal with m=53.
if the standard deviation is 40, it is the result sufficient to
conclude that there is a significant difference?
Fail to reject or reject null hypothesis?

15. To measure the relationship between anxiety level and test
performance, a psychologist obtains a sample of n=7 college
students from an introductory statistics course. The students sre
asked to come to the laboratory 15 minutes before the final exam.
In the lab, the psychologist record physiological measures of
anxiety (heart rate, skin resistance, blood pressure, and so on)
for each participant. In addition, the psychologist obtains the
exam score for each participant.
